Usually, Silica sol casting parts tolerance within GB/T6414, CT5~6, weight range from 20 grams to 50 kilograms, the 

surface finish is Ra6.3.

Silica Sol Casting vs Water Glass Casting,Silica sol castings are mainly used for products with high corrosion resistance 

and precision dimensions, since silica sol steel casting can have much better surface quality and less geometrical deviation of dimensions.

The silica sol investment castings have better dimensions and surface quality, but just more expensive than water glass 

casting. Cost of silica sol casting is almost twice than the cost of water glass casting. Below are the main differences between 

solica sol casting and water glass casting.
